Well I agree about the helping if you resign comment. I think you were right, if it had been your decision to leave then I feel obligated to an extent to help those people I used to work for out  but if you were fired with no warning and they want you to work for free I'd tell them to take a hike.  I mean if you don't have a new job you're spending time helping them and have no income coming in. If you have a new job you're taking time away from family or your free time.  Would your boss give you advice on project management for free if he had been laid off? I am goign to assume no.

I was reading an article on Wikipedia a couple of days ago and clicked on a link in the article. I was brought to this page and figured I would post it seeing all of the True, False and File Not Found Boolean comments on the board.  I don't know why a Unknown Value wouldn't be classified as false but there is probably many good reasons for that.
